The eruption was so intense it punched a crater the size of fifteen Milky Way galaxies into a part of space hundreds of millions of light-years away. Feb 28, 2020 Mysterious objects found orbiting supermassive black hole: study Are they just gas, or are they stars? Astronomers now believe...

The supermassive black hole at the center of our galaxy, the Milky Way, is always up to something unusual. Now, astronomers have spotted strange new objects close by — and they aren't quite sure what they are. Using 13 years worth of data from the W.M. Keck Obs...
Many galaxies are thought to have supermassive black holes at their centres—more than a million times the mass of the Sun. Measurements of stellar velocitiesand the discovery of variable X-ray emissionhave provided strong evidence in favour of such a black hole at the centre of the Milky Way...
This animation shows D9, the first-ever star pair discovered near Sagittarius A*, the supermassive black hole at the center of the Milky Way. We zoom in and out on the black hole and the single stars orbiting it, to then get close to D9, the first ever binary star system found in...
Astronomers have used the Very Large Telescope to discover the first binary stars around the supermassive black hole at the heart of the Milky Way.
“If we didn’t have black holes, galaxies would be much larger,” said Poshak Gandhi, a professor of astrophysics at the University of Southampton in the United Kingdom and a co-author on the new study. “So if we didn’t have a supermassive black hole in ourMilky Waygalaxy, there ...
And at right is the more massive black hole at the heart of our own Milky Way galaxy. (NASA's Goddard Space Flight Center Conceptual Image Lab / NASA) Earth is minuscule compared to the supermassive black holes. It would take 109 Earths to span the diameter of the sun, according to ...
The prominent core of Bode's Galaxy also shines brightly with the light of older, redder stars in this shot, which orbit a monstroussupermassiveblack hole that is estimated to have a mass the equivalent to 15 times that of the Milky Way's Sagittarius A*.—Anthony Wood,Space.com, 30 Apr...
At the center of every galaxy is an immense cosmic engine known as a supermassive black hole. In the Milky Way, that engine is known as Sagittarius A* and it’s the ultra-massive object—around 4.3 million times the mass of our Sun—about which our galaxy, our solar system, and you ...
